Description

Hosting establishment method, device and system

The present invention relates to the field of communications, and in particular, to a bearer establishing method, apparatus, and system. Background technique

In a network deployment scenario, there are two different network nodes, namely, an E-UTRAN NodeB (eNB) and a Small Cell Node (SCN). The eNB and the SCN respectively control one or more cells. The frequency of the cell used by the eNB and the SCN may be different. The cell of the eNB uses the frequency F1 and the cell of the SCN uses the frequency F2. The cell coverage of the eNB is large, which may be called a macro access network node, and the cell coverage of the SCN is small. It may be referred to as a micro-access network node. There may be multiple micro-access network nodes in and around the coverage of a macro access network node. Micro-access network nodes are generally deployed in service hotspot areas to help macro access. The network node offloads traffic in these areas.

According to the number of deployed micro-access network nodes, the deployment scenario can be classified into two types: sparse and dense. In a sparse deployment scenario, the number of micro-access network nodes is small, and one service hotspot may be deployed with only one or a few. Several SCNs; In a dense deployment scenario, the number of micro-access network nodes is very large, and a large number of SCNs may be deployed in a service hotspot area.

In addition, because the service hotspot areas are often discontinuous, the coverage of the micro access network nodes is often discontinuous. A service hotspot area is covered by a cluster of micro access network nodes, and micro-access network nodes of the same cluster are often adjacent to each other, and different micro-access network node clusters are likely to be non-contiguous.

Referring to FIG. 1 , in an existing network architecture, an SCN is connected to an eNB through an X interface, and the SCN and the core network node have no direct connection port, where the core network node includes a Mobility Management Entity (MME) and The Serving Gate Way (SGW); the X interface can be a new interface, or it can be an existing SI interface or an X2 interface; the eNB connects to the MME through the interface Sl-c, and connects through the interface Sl-u. To the SGW; the MME and the SGW are connected through the interface SI1.

In the prior art, the eNB is responsible for forwarding the downlink user data sent by the SGW to the SCN, and is responsible for forwarding the uplink user data sent by the SCN to the SGW. In a sparse deployment scenario, the number of SCNs deployed under one eNB is limited, and the architecture works well. But with the number of SCNs deployed in the network The number of SCNs deployed in an eNB may be very large in a dense deployment scenario. This may cause the following problems to the existing architecture:

1. The data that the eNB needs to forward will increase as the number of SCNs increases. Eventually, the eNB may not work properly due to excessive load;

2. The data carried by the connection between the eNB and the SGW will also increase as the number of SCNs increases, and eventually the connection may be congested.

Illustratively, the gateway node 203 and the core network node 204 can be connected through the user plane interface S1-u of S1, and the gateway node 203 and the macro interface The access node 204 can be connected through the Sx interface; the macro access network node 202 control plane interface S 1 -c is connected to the core network node 204; and the X interface can be divided into two parts: the control plane interface Xc and the user plane interface Xu, The micro access network node 201 is connected to the macro access network node 202 via the interface Xc, and the micro access network node 201 is connected to the gateway node 203 via the interface Xu. The control plane interfaces (e.g., X-c and Sl-c) are used to transmit control signaling or control messages, and the user plane interfaces (e.g., X-u and Sl-u) are used to transmit user data.

Referring to FIG. 3, an embodiment of a bearer establishment method in an embodiment of the present invention includes:

301: The core network node initiates a create bearer request.

The core network node initiates a bearer request to the macro access network node, so that the macro access network node enters the process of creating the bearer.

Optionally, the core network node may be a Serving GPRS Support Node (SGSN), or may include a Mobility Management Entity (MME) and a Serving Gate Way (Serving Gate Way). SGW) network system. Optionally, the macro access network node may be an eNB, or may be a home base station gateway (HeNB GW, Home eNB Gateway) in a long term evolution system, and a home base station gateway (HNB GW, Home NodeB in a universal mobile communication system). Gateway), base station (NB, Node B) or donor base station (Doror eNB, DeNB).

Specifically, in the embodiment of the present invention, the first identifier is allocated by a core network node, and is sent by the core network node to the macro access network node, and then sent by the macro access network node to the gateway node; The three identifiers are allocated by the micro access network node, and are sent by the micro access network node to the macro access network node, and then sent by the macro access network node to the gateway node.

Optionally, the micro access network node may be an SCN, or may be a relay node (RN), a home base station (Home eNB or Home NB), a small base station (Micro eNB), and a micro base station (Pico eNB). Femto eNB, WiFi access point (AP), etc.

Specifically, in the embodiment of the present invention, the second identifier and the fourth identifier are allocated by a gateway node. After the gateway node obtains the first identifier and the third identifier, the micro-access network node obtains the second identifier, and the core network node obtains the fourth identifier, the micro-access network node and the core network node can perform Transfer of user data.

Illustratively, when the micro-access network node needs to transmit the uplink user data to the core network node, the micro-access network node first sends the uplink user data to the gateway node, where the data packet of the uplink user data carries the second identifier. Then, the gateway node carries the second label carried in the data packet of the uplink user data. The first identifier is added, and finally, the gateway node sends a data packet carrying the uplink user data with the first identifier to the core network node.

Finally, the gateway node sends the data packet carrying the downlink user data with the third identifier to the access network node.

As shown in FIG. 2, whether the uplink user data or the downlink user data is transmitted, the user data is directly transmitted through the user plane interface in FIG. 2, and does not need to be processed by the macro access network node, thereby reducing the macro access network node because of user data. The possibility of too much load and too large to work properly; it also reduces the possibility of congestion between the macro access network node and the core network node due to excessive user data.

In addition, in the actual existing network deployment, the SCN-eNB-SGW connection may not always be the shortest, and there may be other shorter connections between the SCN and the SGW. The existing network architecture requires the SCN and the SGW. The data must be transited by the eNB, in which case the transmission delay of the user data is increased. In the network architecture of the embodiment of the present invention, since the gateway node is added, the short connection can be fully utilized, and the user is reduced. The transmission delay of the data.
